Problem B) A mass of 4 kg on a horizontal surface has an initial velocity of 5 m/s when it hits a spring.
The spring compresses by 0.2 m when the mass has a velocity of 0.7m/s What is the spring constant, k, of
the spring?
Problem C) A block of mass 5 kg has a speed of 2 m/s at a height h above a spring (spring constant
k = 1000 N/m). If the spring is compressed by a max amount of 0.5 m, what is the max rebound height
of the block?
